Overview:

 

The Frenzel JF-6G15  "Tube Reverb Preamp"  is part of our "Inspired" line of products inspired by the vintage 50's - 60's amps with the "TONES YOU KNOW.. It is designed to easily plug into either the input jack or the effects loop of  your amp and  give your amp those great classic Fender tube driven  tank coil reverb tones!  The unit is designed for maximum flexibility.  It provides two separate signal paths, one for the normal signal and one for the reverb signal.  The reverb signal is added in by adjusting the MIX control and can be turned on or off by a footswitch.
